恒电量微扰下的过渡过程可用一组线性微分方程组表示,求解的关键是确定其初始条件值。在恒电量扰动瞬间,有溶液电阻和忽略溶液电阻的暂态过渡过程的机制不同,因而极化电位随时间变化的函数关系也不一样。有溶液电阻时,电荷的转移和传输不能瞬间完成,需要一定的传递时间,即极化电位不会发生突变;而无溶液电阻时,依据基尔霍夫定律,在恒电量扰动瞬间,极化电位必将发生突变。同时电路受恒电量控制,无论突变瞬间或电量传递的整个过程都必须遵守电荷守恒原理。以此建立恒电量激励下过渡过程的初始条件。
The transition process under constant power perturbation can be represented by a set of linear differential equations. The key to solving is to determine its initial condition value. At the moment of constant power disturbance, there are different mechanism of solution resistance and transient process of ignoring solution resistance, so the function of polarization potential with time is different. When there is a solution resistance, the charge transfer and transfer can not be completed in an instant, and a certain transfer time is required, that is, the polarization potential does not change suddenly. When there is no solution resistance, according to Kirchhoff’s law, Potential will change suddenly. At the same time the circuit by the constant power control, regardless of the sudden moment or power transfer process must comply with the principle of conservation of charge. In this way, the initial condition of transition process under constant electric charge excitation is established.
